Reflection and Transmission of Guided Waves at the Boundary Between Two Dissimilar Waveguides

Abstract

The reflection and transmission of a thin film guided wave incident at arbitrary angles onto the boundary between two dissimilar waveguides are problems of continuing interest in guided wave technology. The normal modes of individual waveguide with shorting planes are found and the point-matching method is used to satisfy the electromagnetic boundary conditions across the transverse interface between two waveguides.
